♥RULES:1) 1 day rule:-
A fan only can purchase 1 ava per day no matter from which creations.

Example:

Mikuru chan request to buy an ava from miku's shop at 1/4/2010 12pm. Miku finish and post the pic at 1/4/2010 2pm. Then the time will be started counted from 2pm, Steph chan can only request after 2pm on 2/4/2010. In between this 24 hours, Mikuru chan cant request to purchase any ava from other shop. This is too make sure everyone have even chance to buy the ava. .
